Extra component question

Alright, so I know how to make an extra component by rewriting the "print free text" function in my custom theme. However, what I don't know how to do is to mix my custom components with the normal ones. For instance, say I wanted to have:

Custom componentCalendarAnother custom componentLinks

Or something like that?

Using just the Additional Component tutorial, it seems like all I can do is make a bunch of custom ones go right after each other, you know?
